UK angel investment deals come from four main places: angel networks and syndicates, online equity platforms, accelerator and university spin-out programmes, and - quietly doing more work than all the others - your own network. Finding them is less a search than a habit. The angels who see the best companies aren't lucky; they've spent years building the channels that route deals their way.
That's the uncomfortable truth at the centre of this. Dealflow - the stream of opportunities you see over time - is the part of angel investing nobody can hand you. You can buy diligence, borrow conviction from a syndicate lead, even outsource the paperwork. But what crosses your desk in the first place is something you build.
One line before the routes, and we'll come back to it: this is editorial information, not financial or investment advice. We'll describe where deals come from and what to check. What you do with any of it is between you and a regulated adviser.
First, can you legally see the deals?
Before sourcing, a gate. Under Financial Conduct Authority rules, early-stage investments can't be marketed to the general public. To be shown most deals legally, you'll usually self-certify as a high-net-worth individual or a sophisticated investor - someone with relevant experience, such as previous angel deals or a finance background - or invest through an authorised firm that assesses your suitability for you.
The income and asset thresholds behind those labels were tightened in recent years and are exactly the sort of figure that drifts, so don't lift a number from a blog post, this one included. Confirm the current criteria with the FCA or a regulated adviser before you tick any box. Most platforms and networks will ask you to certify on the way in, which is the point at which the gate actually bites.
Route one: angel networks and syndicates
For most British angels, this is the front door. An angel network is an organised group that meets - in person or online - to hear founder pitches and invest together. A syndicate is tighter: a lead angel sources a deal, negotiates the terms, runs the diligence, and others follow into the same round behind them.
The appeal is obvious. You get curated dealflow, diligence done by someone with skin in the game, and smaller minimum cheques than a direct round would demand. The trade is control and cost. You're trusting the lead's judgement, and they usually take a slice of any upside - the "carry" this newsletter is named after - on top of the round's own terms. Worth knowing what you're paying for, and whether the lead's incentives line up with yours.
Britain has a deep bench here, from long-running national networks to regional groups and sector-specific syndicates. The quality varies enormously. A network is only as good as the deals it sees and the rigour of the people leading them - so the membership is the product, not the brochure.
Route two: online equity platforms
Equity crowdfunding sites and curated deal platforms put dealflow on tap. They list companies - many already structured for SEIS and EIS, with the paperwork prepared - and let you invest from low minimums, sometimes a few hundred pounds. The volume is the attraction and the hazard in one: you'll see a great many companies, and the quality control is entirely yours to apply.
Two distinctions matter. Open crowdfunding platforms list deals to a wide pool and lean on the crowd; curated or "members" platforms pre-screen and show a narrower selection to certified investors. Neither model removes your job. A polished listing page is a marketing document, not a verdict, and the headline valuation on a platform is a number the company chose, not one the market tested. Read the deal, not the design.
Route three: accelerators and spin-outs
Accelerators take cohorts of early companies, put them through a few months of intensive support, and end with a demo day where founders pitch to a room of investors. They're a concentrated source of deals that have already passed one filter - getting into the programme - though that filter screens for very different things than your own would.
University spin-outs are the other vein here, especially in deep tech and life sciences. Britain's research universities generate a steady flow of companies built on licensed intellectual property, and many run their own investor channels or partner with funds. These deals tend to be more technical and longer-dated; the diligence demands more of you, and the science is often the part a generalist angel can't fully assess alone.
Route four: your own network
The oldest route, and still the best for many. Founders you've worked with. Operators you backed who are now building again. Deals passed along by other angels who trust your judgement and expect the favour returned. This is proprietary dealflow - opportunities that never hit a platform or a pitch night - and it's what separates the angels who do well from the ones who simply do deals.
You can't buy it, but you can build it. Be useful to founders before there's a round on the table. Be straight with the angels you co-invest alongside. Develop a reputation for adding something beyond the cheque, and deals start finding you rather than the reverse. It compounds slowly, then it doesn't.
The best deals are rarely advertised. They're passed along.
The SEIS and EIS check worth running
However a deal reaches you, one check is specific to investing in Britain. Much of the reason angel investing works here at all is the tax wrapper, and it's worth confirming a company qualifies before you commit. A company should hold HMRC advance assurance - a pre-investment indication that HMRC expects the shares to qualify for SEIS or EIS - and you're entitled to ask to see it. It isn't a cast-iron guarantee, but investing into a round without it puts your relief at genuine risk.
The two schemes sit at different stages. SEIS, the Seed Enterprise Investment Scheme, targets the very earliest companies - trading for less than three years, fewer than 25 full-time-equivalent staff, gross assets under £350,000 when shares are issued, raising up to £250,000 in total under the scheme. For the investor, it offers 50% income tax relief on up to £200,000 invested per tax year, with a three-year minimum hold. (gov.uk: SEIS)
EIS, the Enterprise Investment Scheme, picks up for companies that are still young but larger, offering investors 30% income tax relief on up to £1,000,000 per tax year - or up to £2,000,000 if at least £1,000,000 of it goes into knowledge-intensive companies - again with a three-year minimum hold. The company-side limits (gross assets, the annual and lifetime raise caps, and the longer runway for knowledge-intensive firms) were revised with effect from 6 April 2026. As things stand, a standard company can hold up to £30m in gross assets before the share issue, raise up to £10m in any 12-month period, and raise up to £24m over its lifetime, with knowledge-intensive companies allowed more. For the current company-side detail, treat HMRC's own page as the source: gov.uk guidance on applying for EIS.
Read the relief as what it is - a cushion, not a reason. It softens the losses and sweetens the wins. It does not make a weak company a strong one, and chasing the relief into deals you'd otherwise walk past is how angels lose money with a clear conscience. Sourcing widely exists precisely so you can afford to say no.
Treat sourcing as a pipeline
Pull the routes together and a pattern emerges: finding deals isn't an event, it's a flow you manage. Experienced angels look at many companies for each one they back, because early-stage returns are brutally concentrated and selectivity is the only real edge. Seeing more deals is what buys you the right to be picky.
So the practical move is to keep several channels open at once - a network or two, a platform you trust, the relationships you're slowly building - and let the volume do its work. How much of any of this you act on, and whether you should be investing at all, is a question for you and a regulated adviser. Our job is only to show you where the deals are.
Frequently asked questions
Where do UK angel investors find deals?
Mostly through four routes: angel networks and syndicates, where a lead angel sources and others follow; online equity platforms that list companies already structured for SEIS and EIS; accelerators and university spin-out programmes that run demo days; and personal networks of founders and other angels. The best dealflow tends to be proprietary - passed along privately rather than advertised. This is general information, not investment advice.
Do I need to be a sophisticated or high-net-worth investor to see angel deals?
Usually, yes. Under Financial Conduct Authority rules, early-stage investments cannot be marketed to the general public. To be shown most deals legally you typically self-certify as a high-net-worth individual or a sophisticated investor, or invest through an authorised firm that assesses your suitability. The thresholds have changed in recent years, so confirm the current criteria with the FCA or a regulated adviser before self-certifying.
What is dealflow in angel investing?
Dealflow is the stream of investment opportunities an angel sees over time. Strong dealflow means seeing more and better companies, which lets you be selective rather than backing whatever happens to cross your desk. It is built over years through networks, syndicates, platforms and reputation, and most experienced angels treat sourcing as an ongoing job, not a one-off search.
Should I check SEIS or EIS status before investing in a deal?
If the tax relief matters to you, it is worth confirming that a company holds HMRC advance assurance before you invest - a pre-investment indication that HMRC expects the shares to qualify for SEIS or EIS. It is not a guarantee, but investing without it puts your relief at risk. SEIS gives 50% income tax relief on up to £200,000 a year; EIS gives 30% on up to £1,000,000 (or £2,000,000 with knowledge-intensive companies). This is general information, not advice.
How many deals should I look at before investing?
There is no fixed number, but experienced angels typically review many opportunities for each one they back, because early-stage returns are concentrated in a handful of winners. Seeing a wide flow of deals is what makes selectivity possible. How much you ultimately commit, and whether you should at all, is a question for you and an FCA-regulated adviser, not a newsletter.
